Topic: Swell Circuit vero layout (Read 11402 times)

Here is a vero layout of the Anthony Leo fuzz with a couple minor tweaks from Justin Philpott. This vero is verified.This works best with a high output fuzz with octave capabilities (Foxx Tone Machine, Ampeg Scrambler, Fuzz Factory works too!) into a tube amp. Both trannies are 2N3904. The Electro cap is 10u.

So THAT is what the Peachy Fuzz comes from.This is the swell circuit from the Prescription Electronics Experience pedal. I guess they are the same thing.From R.G "The swell circuit is the same as a distortion circuit published in Popular Electronics in the 60's by Anthony Leo. The way this works is that the swell circuit is DC coupled, and the biasing is such that in the absence of a signal, it it cut off. Putting in a signal makes its DC bias point shift and a very distorted signal appears to slowly increase as the bias shifts."This is the circuit with a Fuzz Factory and then an Ampeg Scrambler http://www.youtube.com/watch?v=2al4eJUecX8

YES the original is foot pedal, and every time you need to swell you need to press the foot pedal all the time, that's why i change to a metal pick, now you can do whatever you want slow or speed defends to your pick how quick you hit the strings. you can do longer delay swell while your pick stay on the string.

My only beef with this is, for the fuzz that is in front of it to swell, it has to be up pretty loud meaning I'd have to change settings all the time. Maybe there's a way to switch the swell circuit on and have it simultaneously take a different volume level from the fuzz?
